Abstract

Procédé et dispositif d'imagerie NMR permettant de collecter des données sur chaque sujet pendant un temps de balayage le plus court possible. Pour ce faire, les données de projection sur le sujet sont collectées dans une pluralité de directions, on détermine une direction dans laquelle le nombre d'échantillons est le plus petit dans le sens de la chaîne en fonction des données de projection, et les données sont collectées par le procédé de Fourier tout en faisant tourner les coordonnées de balayage dans la direction susmentionnée.
